.
2 points on this line are, for example,  (-2,4)  and  (-2,18.33).


The line is vertical (parallel to y-axis).


The slope is undefined.

The equation x=-2 represents a vertical line which crosses the x -axis at the point (-2,0) . Every ordered pair with -2 as its first coordinate is a solution .
so, points are:
(-2,1)
(-2,-1)
A vertical line has undefined slope because all points on the line have the same x-coordinate. As a result the formula used for slope has a denominator of+0, which makes the slope undefined.
